Data Contents
Faulted
It indicates the inverter is in a fault detecting state.
0:Normal 1:During detecting fault state
Warning
It indicates the inverter is in a warning detecting state.
0:Normal
1:During detecting warning (When there is contradiction on the inverter
setting.).
Running1(Fwd)
It indicates inverter’s running condition.
0:Stop / During reverse run 1:During forward run
Running2(Rev)
It indicates inverter’s running condition.
0:Stop / During forward run 1:During reverse run
Ready
It indicates the inverter ready for drive.
0:Except Drive status: 3,4,5.
1:Complete ready to drive (Drive Status: 3,4,5).
Ctrl From Net
It indicates selection state for inputting the inverter operational command
0:Operation command selection(A002) is valid to set.
1:Operation command from DeviceNet is valid.
Ref From Net
It indicates selection state for inputting the inverter frequency command.
0:Frequency command selection(A001) is valid to set.
1:Frequency command from DeviceNet is valid.
At Reference
It indicates arrival frequency detecting state for the inverter.
0:During stop / During accelerate or decelerate
1:Arrival frequency
Drive Status
It indicates inverter status.
